L3130 tail light wiring

I have a 2005 L3130 without the cab and with a manual high/low transmission w/ F/N/R shuttle stick on the column. The guy who had it before me took off the rear lights and hacked up the wiring. I am in the process of putting the stock lights back on there, but Kubota says that I have to buy the entire tractor wire harness in order to just get the tail light harnesses.

I bought two generic four wire harnesses and I am trying to restore the tail light functionality. I have pretty much everything done except for I’m not sure how the brake lights are supposed to be wired.

Two questions:

1: can anyone tell me if when you turn on one turn signal, the other signal light is supposed to come on and be on solid? I assume this is the case since both of mine do it consistently.

2: can someone please refer me to a wiring diagram that has colors and harness locations for the rear of the tractor? If not, can someone take a photo of theirs so that I can figure out which wires go where. I still have a few remaining wires on the right side that don’t meet her out to anything specific and I have nothing I know of to connect the brake light on the left light.

if anyone would like to see, I’m happy to provide pictures of what I have
